Though seemingly harmless, they may be the storehouse of many diseases. These feces can disseminate many dangerous diseases like red-bite fever to bubonic plague. One can know the number of rodents present in their house and their age from the number and size of the droppings.

3. Odor

If one can unexpectedly sniff an unexplained bad smell in their house and notice unusual, exciting activities of their pets, they should be certain that their house is infested with mice or rats.

4. Marks Of Gnawing

Another sign of their presence is the marks of gnawing. Rats have a habit of gnawing all the time. The signs of gnawing on one’s furniture, electric wires, pipes, cloths, etc., indicate their presence. The mice and rats collect the pieces after tearing items for their nests.
